You can use your ranged weapons to make melee attacks that keep foes at bay as you shoot them.
Prerequisites
Perception 7 ranks, Empty Quiver Style, Empty Quiver Flexibility, Rapid Shot, Stabbing Shot, Weapon Focus with the Bow or Crossbow weapon group.
Benefit
While Empty Quiver Style is active, if you successfully hit a foe with a melee attack, any ranged attacks you make until the beginning of your next turn do not provoke attacks of opportunity from that foe.
When using this feat with a crossbow, reloading a crossbow does not provoke attacks of opportunity from any foe you’ve hit in melee. In addition, you may reload your crossbow as if you had the Rapid Reload feat.
